  1. A hospital notices that patient matching errors in the HIE are causing duplicate records. Which algorithm type is most commonly used to improve probabilistic patient matching?

    Answer: Fellegi-Sunter probabilistic matching model

    The Fellegi-Sunter model is the foundational probabilistic record linkage framework widely used in healthcare MPI systems to calculate match probabilities.

  2. What is the primary purpose of the HL7 FHIR Bulk Data Access (Flat FHIR) specification?

    Answer: Exporting large datasets for population health analytics

    FHIR Bulk Data Access enables asynchronous export of large FHIR datasets in NDJSON format, designed for population-level analytics and research use cases.

  3. In FHIR-based HIE, what is a 'Patient $everything' operation used for?

    Answer: Retrieving all resources associated with a specific patient in one request

    The $everything operation is a FHIR extended operation that retrieves all resources related to a patient, providing a comprehensive view of their clinical data.

  4. Which security framework is most commonly required for organizations participating in state and regional HIE networks to demonstrate compliance?

    Answer: HITRUST CSF (Common Security Framework)

    HITRUST CSF is widely adopted as the healthcare-specific security and compliance framework, often required for HIE participation and HIPAA attestation.

  5. What is the key difference between the Consolidated CDA (C-CDA) and the FHIR Clinical Notes Implementation Guide?

    Answer: C-CDA is document-based while FHIR Clinical Notes represents content as discrete FHIR resources

    C-CDA packages clinical content in XML documents, while the FHIR Clinical Notes IG represents the same content as granular, queryable FHIR resources like DocumentReference.

  6. An HIE analyst finds that lab result values for sodium vary between 'mEq/L' and 'mmol/L' across contributing hospitals. This is an example of which interoperability gap?

    Answer: Semantic interoperability failure

    Semantic interoperability failures occur when the meaning or context of data—including units of measure—differs across systems, causing misinterpretation of values.

  7. Which consent model in HIE requires patients to actively agree before their records can be shared?

    Answer: Opt-in consent

    Opt-in consent requires explicit patient authorization before their health records can be accessed through the HIE, offering the highest patient control.
